How can some solid impurities in spent sulfuric acid be removed?
Thread Content
My spent sulfuric acid contains some solid particulate impurities; can a ceramic filter be used to remove these impurities? What is the effect of sulfuric acid on ceramics?
It does not corrode ceramics; fluoride, however, can cause corrosion
Concentration, impurities, content, requirements – various factors need to be taken into consideration.
Filter using a 310H sieve; the mesh size of the sieve can be determined based on the particle size of the particles in the spent sulfuric acid solution.
A fluorine-lined filter is installed at the pump inlet during transportation (which needs to be cleaned regularly)
How high is the temperature? What a high concentration! Corrosion mainly depends on these two parameters!
